Chen's U-Suture Technique for Pancreaticojejunostomy Following Pancreaticoduodenectomy

March 2, 2020 updated by: Chen Xiaoping

Evaluation of Chen's U-Suture Technique for Pancreaticojejunostomy Following Pancreaticoduodenectomy

To date, pancreaticoduodenectomy (PD) is the only recognized potentially curative therapy for malignant neoplasms located in the peri-ampullary region, and is increasingly being used for the treatment of cancer through the resection of the premalignant precursors for invasive carcinomas.Postoperative pancreatic fistula (POPF) is one of the most common complications associated with substantial clinical implications following PD, which significantly affects mortality rate, length of hospital stay, and overall hospital costs. Therefore, the prevention of POPF has always been a high priority for our group as well as other international surgical groups. In 1995, investigators' group established the Chen's U-stitch approach, which was a new technique of end-to-end invaginated pancreaticojejunostomy with transpancreatic transverse U-sutures after PD, and the preliminary results were quite encouraging at that time. Thus, investigators intend to conduct a multicentre, randomized, parallel-group controlled, clinical trial to evaluate the effect and safety of the new technique.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multicentre, randomized, parallel-group controlled, clinical trial to evaluate the effect and safety of Chen's U-Suture technique for pancreaticojejunostomy following pancreaticoduodenectomy. Investigators plan to enroll 960 patients in this study and eligible patients will be randomly divided into two groups. One group will use Chen's U-Suture technique and other group will use classic duct-to-mucosa technique. All patients will be followed up for 3 month after surgery, and primary outcome is POPF, other outcome such as duration of operation, grade of POPF, morbidity, mortality, length of hospital stay, reoperation rate, postoperative pancreatic function and postoperative incidence of chronic pancreatic diseases.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  3. Patients whose pancreatic duct cannot be located.
  4. Patients with history of previous pancreatic surgery, server acute or chronic disease or surgical contraindication.
  5. Patients with HIV-infectious or other AIDS-related disease.
  6. Patients have any condition that in the judgement of the Investigators would make the subject inappropriate for entry into this study.
